IMPROVEMENT IN BOOK-STABBING MACHINES.

Specification forming part of Letters Patent No. 178,147, dated May 30,1876; application filed May 10, 1876. y

To all whom it may concern:

Be it known that we, W. O. HIGKOKand ALBERT COOPER, of Harrisburg, inthe county of Dauphin, and in the State of Pennsylvania, have inventedcertain new and useful Improvements in Stabbing-Machines; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification.

The nature of our invention consists in the construction and arrangementof a stabbinginachine, as used by book-binders, as will be hereinaftermore fully set forth.

In order to enableothers skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruetio'ii and operation, referring to the annexed drawing, in whichFigure 1 is a front View of the stabbingrnachine head embodyingourinvention. Figs. 2 and 3 are crosssections of the same through thelines no as and y y, respectively. Fig. 4. is a detached view of partsthereof.

A represents the head of the stabbing-machine, provided with the shankor arm B, which is placed in suitable guides, so as to have a verticalreciprocating motion. The head A is slotted or grooved longitudinallyfrom its lower edge upward for a suitable dis tance, and in the groovethus formed are placed the needles 0 G, division-plates D D, and the barG. The needles 0 O are of the usual construction, and provided acrosstheir upper ends with a groove, a, as shown in Fig. 4. Between theseneedles are placed the division-plates D D, of any suitable length, soas to bring the needles any desired distance apart. These plates arealso grooved on the front side,-near the top, to form with the grooves ain the needles one continuous In front of the needles and divisionplates is then placed the bar G, which has on its rear side, near thetop, alongitndinal rib or tongue, b, whichlies in the groove formed onthe needles and divisiomplates. This bar or plate G is held to the frontportion of the head A by means of a screw, d, at each end, passingthrough a recess in the head, as shown inFig. 3. In this recess, aroundthe screw d, is a spiral spring, i, the action of which is to draw theplate Gr away from the needles and division-plates; but there is notroom in the head to entirely remove the tongue or rib b from the groove0!, and hence the needles and division-plates will not fall out, but canbe moved easily laterally toward either end of the head. The bar orplate G is pressed down, to hold the needles and division-plates firmlyin position, by means of set-screws h h, as shown. As soon as theseset-screws are loosened the springs i 1 at' once draw the bar or plateGr outward, so that the needles and division-plates may be changedwithout trouble.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the grooved or slotted head A, of the needles 0and divisionplates D, having grooves a, as described, the plate or barG, having tongue or rib b, and the set-screws h, substantially as andfor the purposes herein set forth.

2. The set-screws d cl and the springs i i, in combination with the barG and recessed head A, substantially asand for the purposes herein setforth.

' In testimony that we claim the foregoing we have hereunto set ourhands this 27th day of April, 1876.
